The Ohlins HD003 STX 36 Twin rear shock set is designed for Harley-Davidson Sportster models that need controlled damping and dependable road holding. Built around Ohlins twin-shock architecture, it focuses on stability, traction and predictable chassis behaviour. The damping system uses separated oil and gas to help maintain consistent performance during sustained riding.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed from competition experience and translated into durable, serviceable road components. This unit targets clear feedback and controllable damping rather than a harsh ride. It suits riders who want a more disciplined rear end without compromising everyday usability.

Who this shock is for

Ideal for Sportster riders who push on through corners, carry load, or want improved stability under braking and acceleration. It also suits riders who value adjustability to match different roads and riding styles. If you prefer a set-and-forget cruiser feel with minimal tuning, this may be more adjuster-focused than you need.

Shock design & features

This is a twin rear shock arrangement from the Ohlins STX 36 Twin family. The design uses a separated oil/gas damping system to support consistency and reduce fade during longer, harder rides. Internally, it uses dedicated damping circuits intended to keep traction and control more predictable as conditions change.

Tuning controls

The HD003 provides external damping adjustment for both compression and rebound, allowing you to balance support, grip and comfort. Rebound adjustment helps manage how quickly the rear returns after bumps and throttle inputs, while compression adjustment influences support under load, braking forces and sharper road impacts. These controls are intended to let you fine-tune the chassis response rather than rely on a one-size setup.

Before you install

• Confirm fitment to your specific Harley-Davidson Sportster model and year before purchase.
• Set sag and damping with the bike at typical riding weight to get the best result from the adjustment range.
• After installation, re-check fasteners and settings after the first few rides as components bed in.

Serviceability/lifecycle

Ohlins shocks are designed to be maintained and serviced to keep damping performance consistent over time. Routine servicing helps restore oil condition and internal sealing performance, particularly if the bike is used on rough roads or ridden hard. Proper maintenance also protects the adjustment function and overall ride quality.
